Robinson claims he was privy to incriminating comments from one of Brendan Malone's assistants - although he would not be drawn on the details.
He said: "We felt it (their second goal) was offside and I'm going to make an official complaint about the officials.
"The linesman said something to me that, if one of my players had said, they would have been sent off. I can't say any more or I'll be the one who gets fined.
"There were a few words of lovely encouragement from the official in front of me - I wouldn't condone my players speaking to anyone the way he spoke to me."
